Answer:
If sam had x accounts, then ruby had 9x then:
X + 9X = 120
10X = 120
X = 120/10
X = 12
If ruby had 9x then she had:
9(12) = 108
And Sam:
12
108 - 12 = 96
Ruby had 96 more accounts than Sam
Step-by-step explanation:
The problem says that 10x^2 = 80x. Since x is guaranteed not to equal zero, divide both sides by x; 10x=80. Divide both sides by 10 and x=8
Answer:
t = 60
Step-by-step explanation:
Exponents by the power of another exponent multiply.
-12 · -5 = 60
So in this instance, the value of t would be 60.
7(pi/180)
.5*12^2*(7pi/180)
72(7pi/180)
14pi/5=8.7965
